why does rsync translate user at host into '$RSYNC_RSH -l user host'?

OK then...

Because it would break an officially supported use case (rsh).  It would
also break the lsh utility included with rsync (in the support dir).
The --rsh parameter is for specifying alternative remote shells that are
command line compatible with rsh.

In this discussion we have 2 well known use cases plus a basic design
feature verses a single user's custom solution that could probably be
easily re-customized to be rsh command line compatible.
